All her life, Esther Hopkins has been told she has a mighty fine voice.

Still, she can't believe her luck when just days after moving to town she's invited to sing a solo at the 1923 Independence Day picnic. But the group sponsoring the picnic is not the benevolent fraternal order they claim to be. Worse, they've recruited her father, the town's freshly ordained Baptist minister, to become their chaplain. When they target the immigrant family of her new best friend, Esther must risk her father's anger, the KKK's revenge, and her family's safety to follow her conscience, salvage her friendship, and find the strength to speak truth to power even if it costs all she holds dear.
